Alaska ocean observing system

Alaska Ocean Observing System

  • Regional association under IOOS

  • Part of coastal GOOS

  • Ocean component of GEOSS

  • IPY opportunity


Aoos vision arctic

AOOS VISION: Arctic

  • Users

    - communities

    - subsistence users

    - offshore oil & gas

    - shipping/navigation

    - resource managers

    - climate change researchers

  • Information products

    - ocean circulation models

    - climate change indicators

    - improved sea ice, fog & weather forecasts

    - coastal erosion prediction

    - real-time access to data


Arctic priorities national backbone

Arctic Priorities: National Backbone

  • 4 C-MAN stations along Arctic coast

  • Stream flow gauges at key sites

  • Beaufort tide gauges (also T & S)

  • Better bathymetry & nearshore topography measurements

  • Moored buoys along Arctic coast

  • Network of ice-tethered buoys

  • Continuity of RADARSAT or similar sea ice monitoring

  • Validation/ground-truthing for Arctic conditions of natl space-based sensors


Arctic priorities regional

Arctic Priorities: Regional

  • Improved forecasting of sea ice & fog

  • Cabled observatories at Barrow Canyon, Prudhoe & Mackenzie Canyon

  • Sea gliders & AUVs for autonomous data gathering

  • Sensors to measure sea ice thickness

  • Aerosondes for remote observation of near-shore ice & leads & biological surveys

  • Offshore moorings w/ice profiling sonars

  • Radar coverage for measured ice edge & surface currents & for ice motion & mass balance measurements

  • Ship of opportunity program

  • Wind & wave measurements to mitigate coastal erosion & improve navigation safety

  • Acoustic whale listening devices


Aoos vision bering sea aleutians

AOOS VISION: Bering Sea/Aleutians

  • Users

    - commercial fishing

    - subsistence

    - communities

    - climate change research

    - search & rescue

    - resource managers

  • Information products

    - ocean circulation models

    - sea ice & vessel icing forecasts

    - coastal erosion predictions

    - fisheries/ecosystem productivity


Bering sea aleutian priorities national backbone

Bering Sea/Aleutian Priorities:National Backbone

  • Increase number of buoys & make real-time. Monitor more variables.

  • 5 C-MAN stations along Bering coastline between Bristol Bay & Bering Strait

  • Add tide & river gauges

  • Several long-range HF radar surface current mappers at pulse pts in circulations & major fishing grounds

  • Expand fisheries surveys, increase oceanic parameters measured


Bering sea aleutians priorities regional

Bering Sea/Aleutians Priorities:Regional

  • N-S array of 5 moorings along 70m isobath

  • Moorings across Bering Strait

  • Set of moorings across AK Stream s of Aleutians including shelf break buoys to measure entire water column. 2-3 moorings in Unimak pass, Amukta/Samalga Pass & Amchitka Pass

  • Expand coverage of bottom trawl surveys and BASIS project surveys

  • Record in real-time key indicator species such as whales

  • Ship of opportunity program to add addtl observing points

  • Cable-linked observatories on Pribilofs & Little Diomede Island
